What is the outcome of checking out a rule in Pega?

When a rule is checked out in Pega, the application continues to use the previous version of the rule until the checkout process is completed and the updated rule is checked back in. This ensures that there is no disruption to the functionality of the application, as it relies on the existing version of the rule while a developer makes modifications or enhancements.

This behavior is crucial for maintaining application stability, as it prevents potential issues that could arise from incomplete or untested changes. Once the developer finishes their work on the rule and checks it back in, the new version will replace the older one, and the application will then utilize the latest modifications.

By allowing the application to reference the previous version during the checkout process, Pega ensures that development and testing can occur without affecting the live environment or the user experience.
